A used double-edge blade is still sharp on both sides. Dropped loose into the bin, it can cut through the bag and hurt whoever empties it: you, someone in your house, or the person collecting the waste. The fix is simple: collect used blades in a closed container, and only throw the container away when it is full.
Never throw away a loose blade
Do not put a used blade loose in the bin, in the plastic or packaging recycling, or wrapped in a single tissue. Paper tears and tissue does not stop an edge. Even a blade folded into its old wrapper can slide out.
Option 1: a blade bank
A blade bank is a small closed container with a narrow slot. You slide the used blade in after your shave, and it stays there safely until the bank is full. Because the slot is narrow, the blades cannot fall back out.
You can make one yourself from an old tin or a small jar: cut or drill a slot in the lid, seal the lid with tape so it cannot open, and write "used razor blades" on it. Some blade packs also have a small slot for used blades built in, which works well if you only use one brand.
The DERWAL Blade Dispenser combines both jobs: fresh blades come out at the top, used blades go into a closed compartment at the bottom. The compartment is not meant to be opened. When it is full, you dispose of the whole dispenser, closed, so you never have to touch a used blade again.
Option 2: a sealed tin or jar
No slot? Any sturdy container with a lid that closes well will do, as long as it is metal, thick plastic or glass, and not cardboard. Keep it out of reach of children, close it after every blade, and tape it shut once it is full.
Where does a full container go?
That depends on where you live. Double-edge blades are steel, so some recycling centres accept a full, closed container with their metal. In other places it simply goes in with the general household waste. Check the waste guide or app of your local council, and tell them what is inside if you are not sure. Never put blades in the plastic or packaging recycling.
Handle used blades safely
- Hold a blade by its short sides only, never by the long edges.
- Take the blade out over the sink, so a dropped blade does not land on the floor.
- Put it straight into your blade bank, not on the edge of the sink "for later".
- Do not use your fingers to push a blade into a slot that is nearly full: tap the container or start a new one.
Changing the blade is the moment you handle it most. A Blade Change Helper holds the razor head while you twist the handle off, so you only touch the blade to lift it out and drop it in the bank.
In short
Collect used blades in a closed container with a slot, close it well when it is full, and follow your council's rules for the full container. It takes a few seconds per shave and keeps everyone who handles your waste safe.
